As with any release, there's a lot of incremental improvements wherever we find opportunities, and there's a couple of new features. The two most interesting new features are:

The Code Analyzer which reports possible errors in your application, both dynamic (ie memory access errors), and static. The static error detection is the newest feature, this goes beyond the compile time warnings or lint messages, and does much more detailed compile-time analysis of your code.

Remote development on Windows. I'm yet to try out this feature, but the IDE has the ability to run remotely on a Windows box seamlessly compiling and running on a remote server. In fact the improvements in the IDE are well worth a look.
